Problem/Motivation

When using migrate:status without any migration IDs, we're encountering PHP Fatal error: Allowed memory exhausted errors.

PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 45056 bytes) in /var/www/docroot/core/lib/Drupal/Core/Database/StatementWrapperIterator.php on line 113

Prerequisites
Drupal core version 10.3.2
Migrate Tools version 6.0.4
PHP memory_limit 256M

Steps to reproduce

  1. drush si demo_umami -y
  2. drush en migrate_drupal migrate_tools -y
  3. drush migrate:status

Observe error

Proposed resolution

Pending 💬 Why does MigrateToolsCommands::migrationsList() utilize MigrationPluginManager to instantiate all plugins ? Active , replace

MigrateToolsCommands::migrationsList() usage of MigrationPluginManager here

    if (empty($migration_ids)) {
      // Get all migrations.
      $plugins = $manager->createInstances([]);
      $matched_migrations = $plugins;
    }

with something like the following, but using dependency injection

$migrations = \Drupal::EntityTypeManager()->getStorage('migration')->loadMultiple();
$migration_ids = implode(',', array_keys($migrations));
